Assign `tabId` to middleware request, if provided (#7695) The `tabId` of the message sender is now added to the middleware request object. This step is omitted if the `tabId` is not provided. This is done early in the middleware stack, so the `tabId` should be available for any subsequent middleware to use. The Onboarding Middleware has also been modified to get the `tabId` from the request object, rather than expecting it as a parameter upon creation. This refactor will enable further uses of the `tabId`.
